Rodeo Days - S4-E12
Deliberate mistake: When Bobby is trying out for the cattle roping at the rodeo, he gets the rope tightly around the calf's neck. As the calf starts to drag Bobby you can see the rope is now very loose around its neck. A little later when the clowns are chasing each other the rope is back tightly around the calf's neck. May be deliberate as it may look like the calf would have been choked with the rope being so tight around its neck.
Returning Japanese (1) - S6-E21
Plot hole: In this episode, Hank meets his paternal half brother. They look alike. However, we saw in an earlier episode that Hank's facial structure takes after his mother, not his father. Since they are paternal half brothers, then the Japanese brother cannot look like Hank since he has a different mother.
Peggy: It was like a knife in his heart when she stuck that fork in his back.
Death of a Propane Salesman (2) - S3-E1
Question: Why does Kahn act so emotional about Buckley (especially when he criticizes Luanne for not crying)? Even though he says that he sought Buckley out and got to know him, there haven't been any signs of him befriending Buckley until now.
Answer: Mainly, Kahn wants to annoy Hank by praising Buckley, because Hank did not like Buckley. Also, when a person dies (or some other tragedy happens), there are often people who "use" the incident to get attention for themselves. They act like they are more involved/close than they really are. At least in my experience.
Answer: Because Kahn doesn't like Hank and Buckley annoyed Hank so much.
